Abstract

Failure to detect parity-nonconserving effects in atomic transitions coupled with the available neutrino neutral-current data would appear to rule out all SU(2) ⊗ U(1) gauge theories which respect "natural" conservation laws for charm and strangeness and quark-lepton symmetry. We analyze a left-right symmetric "natural" (in the above sense) and quark-lepton symmetric SU(2)LSU(2)RU(1) gauge theory and find that it accommodates all the features of neutral-current phenomena.
